ANT'IGWE Dnylcn ronntr'roidonnn Application flied-Annet 3 19,22, Seriell-'1%. 529MB# l In driving` -antomobiles the eyes of the '.50 arranged adj'aoent each other.

.driver arefoften daznled by the glare of the sun or by the glare ofthe headlights of nn approaching nntomoblleend vario-us devices hare been proposed and used to overcome .this trouble, some of the more'common being to provide n piece. of colored glass' to be placed 'on thewind'shield in iro-nt off-'ie drivers eyesor to provide means torentier a section of the windshield glass opaque as. by painting a black section onv it or lsuspending an opaque member in front of the' flass and in line withl the vision of 'the river. This latter ,arrangement is preterable from the standpoint of ellieiency bfor itI absolutely prevents any glaring light from reach-ing the eyes of the driver. However, it has the substantial disadvantge that it, tires the eyes and also is annoying to many driversv tohave n darli object, be-'` V*foretheir eyes continuously.

'I he object ,of my invention is-to provide an improved form oflanti-glnrc device for yvindshields whicln While it prevents the passa-ge ofiany light directly through it-is at.'Y

. the same time the seme color as the windshield glass so it avoids the objections set'.

Accordi-ng to the preferred form of my invention l provide an anti-glare device in the form of a glass prisrnarranged on the `windshield glass -nt height in line vwith the eyes of the driver so it otehe's light coming from the sun or from the headlights of an approaching :intoniobile'nnd refleets and refrncts 'the same, rI "he prism is preferably made of clear glass so it is the same color. as the -winrlshield glass and hence does not have the tiring and annoy ing effect of .a dar-k object in front of the eyes. The p'rism may be formed separately and v be' suspended on the Windshield by' a suitable frame which is preferably adjustable, or it may -be mold es a. part of the windshield gla. Or, if desired, it'. may formed v separately and then" cemented to the'. Awindshield glass. Also, instead of a single prism I may use two or more prisms In thefdra-Win Fig. l is s view of a wind-shield provi ed with'an' :mtb-glare device embodying my invention; Fig, 42 .isa perspective *view of the' device; FigLIB shows 55. a modification wherein the prism is. ce mented lto the windshield glass; nd Fig. 4-

is a .modication sho'riding,"en` rra'ngement ably fastened together. y

be understood that vthe ira-nie illustrated 1s v wherein the prism is formed as an integral part; of the wind-shield glass.

.Referring to me among, Fig-s; 1 and' 2,

indicates a windshield of :in automobile and To glass.prism'supported on the windshield by a suitable adjustable frame. In the present instance the frame comprises twol side members 8 and 9 each formed of two overlapping pieges held together by a set` screw 10, which passes lthrough a slot 11 in l nre fixed in position by set serews 13! The' side members are held in spared rel-ationA to @zich other `by a cross -pieee 14 and at 'their lower endsl they carry lsockets 15 .and

16 in which the' ends of pris-1n 7 are loceted. The sockets and side members. of the frame -x-nay he -Jformed vintegral Awith each other 'or they may be 4formed separately and suit-,1 l

In will of course.

butone'form whichmaybe used md that-A any other suitable found desirable.

In use' thefrnnie' is 'fnstlened to' thewind. shield by hooks 12 and 12 and set screws 13 y and is adjust-ed by mea-ns of set. screws 10 to bring the prism to' the desired height to. suit the individual driver, Then drivin the driver watches the road, usually his si e 'o the road, by looking throng-h the-@windshield to one side of the prism. The prism;l

however, stands infront-'of .his eyes .and

form may used if effective. The prism will reflect. and refraet all llight, striking itso A.that 'none of the-light rays will iin'd'their way directly to the 'drivel-s eye, As is -Well kno-tm all light rey-sst-rikings prism virre either reflee-ted or ref racted, none parsing. directly through the prism.

In Fig. 3 `isillustrated@ error'agonie'nti.- whe'rein instead of :the prism 7 being car ried by 4a frame it is cemented to the windshield-,glass itself.4 In such sense, since 'the pri-sm is not then adjustable, I preferbl'y *use two or more prisms ,arnet-n'gedV one' above'.

the other s shown so as 'meet 'the requirements of.` different drivers. Inwrthepresent instenoe, l'. hdvesbown two 7 formed :integral with'ea-ch other, end

`vend pieces V17 which provide 'at :sul-faces' .18 for oementing t. to windshield glass.v

Preferably it will' be .placedon 'theinside of the glass.

In Fig. 4 I have shown a further modifi? cation wherein the 'prism 7 is formed 'inregrai with the windshield glss 6, a plurality of prisms being `used 'in this case also" for 10 the reasons -stated in connect-ion with* the descriptionof Fig.' 3.

I n actual use I-h'a'e found a 60 prism approximately six inches long' and htx-Ying aces about tivo inches wide to be satisfactory, but it will be' understood that Vprisxfns 'of any dimensions foundjsutable may be used. The prism may be used with n flat side towardthe driver or any Vother angle, for in any case it will reflect and :eefraet the light striking' it. l

As pointed outvvabove, one of the advantages of my device is that it, does not til-e the eyes for `While4 the. driver eannot'see through it, still itis the same color a-sthe Windshield `glass, and blends into it'so it does not produce the effect of having n dark yobject continuously' in front of the eyes.

It will be understood o .f course, that in.- stead of having only e. single prism carried bythe adjustable frame, two or more r-isms may he carried' by it and they may. e ar'- ranged in anysuitahle manner.

In vadcordance jwith the provisions of the l' patent sta-tuus,- I .have described the prin-v ciple of operatono my invention, together with the apparatus Whichi :10W consider to represent the best embodiment thereof', but' I desire to have it understood' that the ap# params shown is only illustraties und thatV sa. f '1.665.964'
